Summary

Partial fix for #8635 – removes antd Select from two settings-related files:

• ProjectSettings/GitHubSettingsModal/GitHubSettingsModal.tsx
• ErrorsV2/GitHubEnhancementSettings/GitHubEnhancementSettingsForm.tsx

Both files used import { Select } from ‘antd’ for the GitHub repository picker. This PR replaces them with the native ComboboxSelect from @highlight-run/ui/components, which provides the same searchable dropdown functionality while staying consistent with the Highlight design system.

Changes

• Replaced antd Select with ComboboxSelect from @highlight-run/ui
• Converted option format from {id, label, value} to {key, render} (ComboboxSelect expected format)
• Added valueRender to display the selected repo name
• Added onChangeQuery to enable the built-in search/filter input
• Added clearable prop and emptyStateRender for consistent UX
• Preserved all existing functionality: search, selection, clear, and disabled states

/claim #8635

How did you test this change?

Verified the TypeScript types match the ComboboxSelect component API. The ComboboxSelect component uses @ariakit/react internally and supports the same searchable select behavior as the antd Select with showSearch enabled.

Are there any deployment considerations?

No. This is a purely frontend refactor with no backend changes.

Does this work require review from our design team?

No – the ComboboxSelect component is already part of @highlight-run/ui and follows Highlight design system. The visual appearance will match other uses of ComboboxSelect throughout the app.
